I've got a short 10 day cross country credit card tour of Korea coming up next Friday and I was thinking of bringing my new Macbook Air (it has a solid state drive instead of traditional, more fragile hard-drives) and my Lumix LX5 camera, for sure. I'm worried about three things that could possibly damage my electronics.

First, the sun. The sun here is merciless and I think the inside of my Wingnut backpack or Ortlieb panniers may become a sauna on wheels. I suppose I could crack open my backpack or panniers a bit to let the heat dissipate. Would that be enough, though?

Second, the rain. If it isn't blazing hot, it's pouring and still warm. I think the Ortliebs got that covered, though, right? The Wingnut cycling backpack, though supposed to be waterproof as well, is more like water resistant. I'll be using that, though for things like my iPod, credit cards, water bladder, little bits and pieces including my camera which I have protective Kata case that can attach to the waist strap. It also has a rain / heat reflecting fly I can pull over the case.

Third, the poor conditions of the road. I think the steel frame, fat tires (38s), sprung Brooks, and my body (if I carry the Mac on my back), can help absorb the shock. I mean, the roads are pretty crap here in the metropolitan Seoul area. I can only imagine how bad country roads are.

One complication is that I'll be carrying a Hiplock chain lock on my waist. If I put the Mac in the backpack and the chain lock on my waist, both of which have protective cases, could the vibrations be damaging?

okay, sorry for the long post but this is important to me. Any input would be appreciated. If it is too risky, I can just leave the notebook at home.
